The .Clinkerf' cooling 'gratebengcovered with lumps or pieces'of clinl/{e'r of' various/sizes, it Vwill 'be `seen'"that-.the air floWingv up througlrjtho "grate openings and the, clinker, will .be

highly heated. before reachingthc vcombus'- 110 tion grate; the result being that the combustion on-the latter grate is more rapidy and thorough than would be the case if the air were supplied cold or only moderately heated. i A For the purpose of removing the cooled clinker from the 'clinker-pit the grate 2G, which receives the. clinker from the combustion chamber is in the form of an endless belt,.trayeling overa pair of drums 31, 32,

the bars of which the traveling grate is composed being arranged parallel -With the axisof the drums and pivotally connected together 1n any suitable manner, not shown.

-One of the drums, for example the rear drinn 3l, may be rotated by any convenient and'suitable means,`nctshown, to actuate4 the. grate, and such rear drum is preferably 26a, 2Gb, at each sidei of the clinker-pit. lt

-cooled clinker from the clinker-pit.

will of course be understood that the movable cli'nker-cooling girate is not in motion except when it is desired to remove the The mouth. of the clinker-pit'is at other times closed by a vertically Stringing door connected to suitable coiu'iter-Weights, one of which is shown at 36'. The outer portion of -thesaid docris formed as a box 3T to in` close the drum 3l and projecting portion of the grate, the ends of'said box being slotted as shown at 38 to accommodate' the journals of. the drum mentioned., The air chamber 27`n1ay be provided with a clean-out open- Ing 139, normally covered by a moyable closure 40. Y

As will be recognized, the apparatus de scribed is an eiiicient means for handling and dispcsing of the clinker for the purpose beforelmentioned, the clinker being deposited on the clinker-cooling grate expeditiously. and with practically no loss of heat. After the heat oi' the clinker has been imparted to the air flowing through the same, the clinker is read-ily delivered to the car,

leaving the cooling grateclear and ready for another'load from the combustion ch a in ber.

The embodimentdescribed is, as just stated. simple in ccnstunction and vconvenient in operation, but it is to be 4understood that the invention may beemliodied in other forms. without.departure from its proper claims.

claim: l

l. In a destructor furnace, in combination, a grate chamber in which the combustion takes place, a clinker-pit below the grate chamber, an air chamber below the' clinker-pit, a `reciprocating grate betweenv the grate chamber and the clinker-pit, lto support theburning materiahand adapted', when actuated, to discharge hot clinker into the clinker-pit, a belt grate movably mounted between theclinkerepit and the air chamber, arranged to receive the clinker. discharged from the grate' chamber into the clinker-pit, and adapted, When actuated, to remove the clinker from the-,clinker-pit, and means for supplying a current of air to the air chamber. v

Q. In a destructor furnace, a grate chamber having a reciprocating grate mounted therein, a clinker pit substantially below said grate, a belt grate niovably mounted in the clinker pit, means 4whereby said reciprospirit and scope as defined by the appended' eating grate uniformly distributes massesvare substantially ,ccextensive with the horizontal dimensions of the aforesaid chambers and located between the grate chamber and the clinker chamber. a receiving chamber for said grate extending outwardly from one of the aforesald openings and in alinemcnt with said grate, means for withdrawing the 105 grate -from the grate chamber into the receiving chamber. to discharge'clinker from the grate into the clinker chamber. a belt. grate substantially ccextensiye With the located between the clinker chamber and the air chamber and in alinement 'with another of said vlateral openings. actuating means for moving the upper surface of said tioned opening to' discharge the clinker from i the clinker chamber. and means for supplying a current of air 'to the air chamber.
